Underwater battle

"When Sail warriors fight, they chase you to the water, drag you into it, and fight you there. So today's lesson is underwater battle. Get ready and hold your breath."
Roleplay starting line(any member can join)(optional): Svachsa glanced at Chance, who was fully concentrated on trying to right herself in the water to attack Thunder. She nearly sighed. Chance was forgetting her lessons again. Always remember to look behind you unless you're backed up against something. Dragons might sneak up on you. Which is exactly what Svachsa is doing right now.

Poor Chance, she's about to get jumpscared by Svachsa from behind XD
As for how they fight in the water without breathing, I suppose dragons can hold their breath for about thirty minutes or so.

mainly focused on getting the effects right here
